It is also called super-realism or hyper-realism and painters like Richard Estes, Denis Peterson, Audrey Flack, and Chuck Close often worked from photographic stills to create paintings that appeared to be photographs." [5]
Until 3D computer modeling became common, architectural renderings were generated by hand. There are still architectural illustrators who create renderings entirely by hand, as well as illustrators who use a combination of hand drawing/painting and computer generated color and/or linework. Common mediums for hand-done architectural renderings ...
Realistic 3D rendering requires finding approximate solutions to the rendering equation, which describes how light propagates in an environment. Real-time rendering uses high-performance rasterization algorithms that process a list of shapes and determine which pixels are covered by each shape.
A normal shader (left) and an NPR shader using cel-shading (right). Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism.
Modern 3D computer graphics rely heavily on a simplified reflection model called the Phong reflection model (not to be confused with Phong shading). In the refraction of light, an important concept is the refractive index ; in most 3D programming implementations, the term for this value is "index of refraction" (usually shortened to IOR).
The processing of architectural spaces without the use of paper and pencil tools is now a widely accepted practice with a number of computer-assisted architectural design systems. [ 14 ] Architectural modeling tools allow an architect to visualize a space and perform "walk-throughs" in an interactive manner, thus providing "interactive ...
However, quickly rendering detailed 3D objects is a daunting task for traditional Von Neumann architecture-based systems. An early workaround to this problem was the use of sprites, 2D images that could imitate 3D graphics. Different techniques for rendering now exist, such as ray-tracing and rasterization. Using these techniques and advanced ...
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
